Description
Data Sheet
| Biological Activity | The specific activity was determined by the dose-dependent stimulation of the proliferation of human MO7e cells (human megakaryoblastic leukemia cell line) and is typically 0.03-0.2ng/ml. |
| Description | IL-9 Human Recombinant produced in HEK cells is a glycosylated monomer, having a molecular weight range of 38-48kDa due to glycosylation.The IL9 is purified by proprietary chromatographic techniques. |
| Expression host | HEK. |
| Formulation | The IL9 was lyophilized from 1mg/ml in 1xPBS. |
| Physical Appearence | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Protein Background | Factor that is thought to be a regulator of hematopoiesis. It has been shown to enhance the growth of human mast cells and megakaryoblastic leukemic cells as well as murine helper t-cell clones. IL-9 is a glycoprotein with a molecular weight of 32-39 that is derived from T-cells, and maps to human chromosome 5. |
| Purity | Greater than 95% as obsereved by SDS-PAGE. |
| Solubility | It is recommended to reconstitute the lyophilized IL-9 in sterile water not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized IL-9 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL9 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Synonyms | P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine. |
